T 0 all whom, itviuzg concern:

Be it known that I, JOSEPH CAsPnR WA- LIER, a citizen of the UnitedStates, anda resi-.

dent of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful improvements in Machines for Molding Confections, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact descripiion.

ihis invention relates to improvements in machines for molding confections; and it has special reference to the machine shown and described in my United States Patent No. 524.,097, issued August 7, 1894, in which patent the'machine comprises a hopper for containing the confection material to be molded and provided with discharge-openings in its bottom, valves and plungers controlling the discharge of the confection material through' said openings, and trays carried upon a conveyer below the hopper and providedwith molds, into which thefmaterial is deposited.

The objects of my invention are to provide more eflicient,. positive, and reliable means for operating the aforesaid plnngers and valves and also to provide simple and efiicient mechanism for automatically and intermittently moving the conveyor to bring the rows of molds provided in the trays successively under the aforesaid discharge-openings.

lit has been found in practice that at each discharge of the confection material from the hopper there is a tendency to leave a string of the material between themolds and the dischargeopenin, ,s. Therefore another object of my invention resides in providing means whereby the aforesaid string is broken before the tray is shifted, andthereby cause the stringto drop into the mold, which would otherwise be strewn between the molds.

My present invention consists, first and essentially, in the combination, with the main frame, main driving-shaft, a hopper for containing the confection material and provided with discharge-openings in its bottom, outoff val vcs, plungers, and oscillatory dischargevalves controlling the discharge of the confection material from the hopper, of a conveyor consisting, preferably, of endless chains below the hopper, trays carried on the conveyor and each provided with a plurality of. rows of molds, a double or duplex ratchet mechanism connected to the conveyer and having a primary actuation by which the couveyer is moved intermittently to bring the rows of molds of'each tray successively under the aforesaid discharge-openings, and a second ary actuation, which is timed to impart a single and greater movement to thcconveyer at regular intervals to bring the first row of molds of each succeeding tray under said openings, and means transmitting motions "from the main driving-shaft to the aforesaid ratchet mechanism and valves and pl ungcrs, respectively.

, The invention also consists, in combination with the main driving-shaft and conveyerchains, of longitudinal flexible bars supporting the portion of the chains below the hop per, cams mounted on-a shaft below the chains, upon which cams the aforesaid bars rest, said cams being timed in their movement to drop and raise the conveyor with the tray immediately after each discharge from the hopper to break the string of confection material formed between the discharge-opening and mold incident to each discharge, as hereinbefore stated, and means transmitting motion from the main driving-shaft to the cam-shaft.

The invention also consists in the novel details of construction, as hereinafter fully described, and specifically set forth in the claims.

In the annexed drawings, Figure l is a side elevation of myimprovedconfection-molding machine. Fig. 2 is a front or end elevation of the same. Fig. 3 is an enlarged vertical transverse. section on line V V in Fig. i. Fig. f is an enlarged vertical longitudinal section on line \V W in In. 2. Fig. 5 is an enlarged vertical longitudinal section on line X X in Fig. 2. Fig. 6 is a vertical transverse section on line Y Y inFi'g. 5. Fig. 7 is a further enlarged detail transverse section illustrating more clearly the cut-off valves, plungers, and discharge-valves winch control the discharge of confection material from the hopper. Fig. 8 is also a furtherenlarged horizontal transvers'e'section on line Z Z in Fig. 4. Fig. 9' is an enlarged detail side view'of the double or duplex ratchet mechanism which intermittently moves the .2 semis conveyor. Fig. 10is an enlargeddetail end view of a portion of the hopper, illustrating the connection between the oscillatory discharge-valves. Fig. 11 is a detail side view of the cam mechanism .which drops and-raises the conveyer. Fig. 12 is an inverted plan view of a portion of the bar which carries the cut-off valves. Fig. 13illustrates thecooling apparatus used in connection with my improved confection-molding machine, which apparatus is partly shown .insection.. Fig. 14 is partly a longitudinal section of the coldair box and a portion of the molding-machine, illustrating a modification of the con.- veyer and molds. Fig. 15 is anenlarged detail plan'view of a portion of .a 'carriermount- 'ed on the conveyer and provided with molds. Fig. 16 is a longitudinal transverse section on lines 1 '1 in Fig. 15.

Referring to the drawings, A represents the main frame of the machine, which frame may I be of any suitable construction or design, and B denotes the main driving-shaft journaled on the lower part of the frame.

Upon the frame A is supported the hopper G for containing the confection material to be molded, which hopper is -,provided in its able horizontal .bar D. ,1 preferably attach said valves to the bar by providingannular recesses ff in the under side of the bar and form each of said valves with a flange g at its upper end, which flanges are seated in the ,recesses,.and to the under side of the bar is secured a plate h to retainth'e flanges t-herein.

To the upper side-of the bar -D are con- :nected two pitmen l 1, which are secured ver-- tically movable at their upper. ends in 'fricrtion-sleeves i 2', provided with journals jj, by'

which said'sleeves are suspended from a shaft E, journaledon an auxiliary frame F, whichlatter frame is supported on the hopper C,

"The sleeve 2' is split longitudinally andformed with ears 2 2, through which earsascrew passes, whereby the sleeve can be compressed more or less to regulate its frictional holdon' the pitmen 1..

Thepitmen 1 .1 receive intermittent 'rec ip-'- downwardly-extend'ingarm ,to the lower end of each of which arms is pivoted a coupling, eye I, sliding on the pitmen l and engaging two stops m m, secured to the pitmen,.wh ere by the bar .D is raised and-l lowered, and, thus the cut-off valves 11 cl, carried thereon, are

the plungers -n 4z, as hereinafter explained;

The shaft- ,E derives its' motion from the "mil-tent; movement wherebythe molds of- .of a sprocket-chain 70", traveling on two sprocket-wheels Z and m, secured to the shafts E and B, respectively.

The hopper G isheated preferably b means of steam or hot-water pipes n" n which surround the hopper for the purpose 'of maintaining the confection material in the hopper in proper'conditiou for being molded, although any other suitable system for heating the same may be employed.

J J denote apair of endless sprocket-chains, which constitute the main con veyer. Said chains travel on sprocket-wheels K K,

mounted on shafts L L, which shafts are journaled in boxes '0 0, secured longitudinally adjustable on extensions M M,provided on the front and rear ends of the main frame A. lSaid adjustment serves to regulate the tension of the chains in the well-knownmanner.

:The chains J J are provided at regular intervals throughout their length with hori-, .zontal plates p the trays 0 Q,- provided with a plurality of 10 ,upon which are supported rows of molds q q to receive the discharges from the hopper, as will be shortly explained.

The chains J J have a primary or intergeach trayare brought successivelyunder the parted by my improved double-or duplex,

. a screw or bolt 4''.

- discharge-openings a a and also a secondary or-smgle and greater movement whereby the a tray is moved to bring thefirst two rowso'f molds of each succeeding tray under the aforesaid opening, which movements are imratchet mechanism,which I will now describe. To one of the shafts L, preferablythe shaft at the front end of the machine, are rigidly secureda primary ratchet-wheel A and a secondaryratchet-wheel B, which ratchet-wheels are detachably secured together by means of To the frame A is pivoted a vertically-disposed"rocksarm C, provided with two longitudinalslots s s" on opposite.

sides of thepivot.

t and'u' denote an upper and lower pitman, respectively, which pitmen are screw threaded at their ends and provided thereat with couplings 'v' o and w w, respectively. The rear couplings are pivotally secured in the aforesaid slots s s. of the rock-arm O and the front couplings are pivotally secured to the outer or free ends of arms a: 01;, respectively, which arms are mounted loosely at their opposite ends on'the aforesaid shaft L. To the front coupling '1) of the pitman t is pivoted a pawl y, which engages the secondary ratchet-wheel B, and to the arm :0, adjacent to the coupling'w' of the pitman u,

is pivoted a similar pawl a, which engages the primary ratchet-wheel A. The rockarm' (3 is operated by means of a pitman a connecged at its lower-end to said arm, as shown at 5, and at its upper end-to an eccen-' tric (DE-mounted on the shaft E, which receives motion from the main driving-shaft A,

as aforesaid. The primary ratchet-wheel'A is provided with consecutive teeth "b b,

whereby it is actuated by the pawl 2' at each thrust of the pitman 11., whereby the'conveyer-chains J J are moved intermittently until all the rows of molds q'q in each tray have been brought under the aforesaid openings, at which time the secondary ratchetwheel B, provided with two teeth I) b, ar-

ranged equally distant apart, is engaged by .the pawl y", actuated by the pi'tman t, which has a greater thrust. than the pitman .u', whereby-the aforesaid chains are given a single and greater movement to bring the first two rows of molds of each succeeding tray 0 under ,the discharge-openings a a.

The thrusts of the pitmen t. and u can be shortened or lengthened to move the chains a corresponding greater or less distance by shifting the rear couplings v w in the slots s "8', provided in the rock-arm C, which rock-arm is so timed ,in its movement as to actuate the ratchetmechanismmnd thus shift the chains J J between each closing and opening of the discharge-valves a a. e

Extending transversely across the juaiu frame A'are two rods 0 0?, preferablysupported on brackets (1 d secured to the extensionsM: Mof the frame, and, upon said rods are supported the ends of two longitumediate portion o theichains' J, J, below the hopper O, are supported. Said bars are-preferably divided intermediate their lengths and connected ther'eat by a flexible plate f,

whereby they will yield under the weight of dinal bars e e, upon which bars 'the inter- 'IOO saidchains, as-will to shortly explained.

Below the bars :2 e extends ,a transverse shaft E, journals-d on the main frame A, upon which shaft are mounted two cams g g, upon which cams the aforesaid bars rest,

said cams serving to allow the bars to yield as aforesaid and to raise the same, thereby lowering and lifting the chains J J, whereby the string of confection material formed between the discharge-valves a a and molds q after each discharge from the hopper wil l be broken, as hereinb'efore stated.

The cam-shaft E is provided with a sprockfet-wheel h which engages the sprocket-chain 70, whereby it receives motion from the main driving-shaft B.

Referring to Fig. 1-3 of the drawings, illustrating the apparatus employed in connection conveyer-chainsC C provided with trausverse boards a. and carried on the sprocket wheels D D, journaled on a support b? at the front end'of the box A; and on rear sprocketwheels mounted on the shaft -L, (not necessary to be'shown in detail,) whereby the latterconveyer-chains receive their move ments. In the box I prefer toprovide tracks c 0 upon which the chains (3 C ride. plemental conveyor is arranged in the same plane as the main conveyor, whereby it will receive the trays-O 0, containing the molded material, and carry said trays into the box A whereby the material will be cooled as aforesaid. The front end of the box A is' provided with an opening f of sufficient size to "permit the removal of .the'trays O 0. I do not wish tolimit myself to the particular construction of. the cooling apparatus herein shown and described, 'as the same is subject to many modifications, or any other suitable means may be employed for the purpose.

The operation of my improved confectionmolding machine is as follows The con veyer chains J J arefirst adjusted to bring-the fi rst tray 0, with its first two rows of molds q".q,

'under the discharge-openings a a in the bottom of the hopper O. The discharge-valves;

of a being closed, the cut-0E valves cl d raised to open the ports 0 c, and the confection .ma-

te'rial deposited in the hopper O, the drivingpulley A is thrown in connection with. the

main driving-shaft A by any suitable or well-v known clutch mech'anismin the usual and well-known manner, (not shown,) and motion.

is transmittedto the shaft E by the sprocketwheels I and m and their connecting sprocket chain is, and by means of the eccentric I,

mounted on the latter shaft,"the plunger-carrying frame is li-lted,wherebythe plungers n n are raised,thereby causing a suction, by which the confectionmateriallis drawn through the ports a 0 into the gage-tubes b b. When the plungers have reached the end of their upward stroke, the bar Dis forced downward by means of the eccentrics G G and their connect ing pitmen '1 1, whereby the cut-off valv'escarried on said bar are caused to close theports c 0. While said yalves are in their closed position, the oscillatory discharge-valves a a are opened by means of the disk 2', secured to the shaft E, and its connecting-pitman 7i, and.

immediately thereafter the plungers 'n. n are pushed down, whereby the confection material is forcedout of the tubes 1) b, from whence the material drops into the molds q q, con- -tained in the tray 0. The discharge-valves a a" are then closed. The lost motions provided for, the pitmen'Z L and the pitmen it serve to properly time the movement of the cut-off valve and discharge-valve, as hereinbefore described. Immediately after the confection material is deposited in the molds and the discharge-valves are closed the conveyerchains J J, carrying the trays '00, are given a sudden drop by the cams g g", whereby the string of material usually left between the molds and discharge-valves is broken and caused to drop in said molds.

Referring to Figs. 14, 15., and 16 of the drawings, illustrating a. modification of the.

E and eccentric-shaft E being in the amine gear with the main driving-shaft B, it willbe seen that the cams are so timed in their movement as to drop and lift the conveyerrchains J J after each discharge of the materia'lffrom shifted to bring the two succeeding rows of the tray 0 under the discharge-openings of the hopper by the primary ratchet-wheel A,

which is moved by the pawl z, actuated by tlge rock-arm C, connected .to the eccentric c repeated after each discharge from the hopper until .the last tworows of-molds'q' q in movement by reason ofgreater thrust ofithe Theoperat-ion of said ratchet-wheel is I I Immediately after the chains J J are raised or lifted by the cams they are the tray are filled, at which time. one of the teeth b} ofthe secondary ratchet-wheel B is brought into position to be engaged-by-thepawl y', andthereby given asingle and greater;

pitrnan t, as aforesaid, whereby the chains. J J are'shifted sufficiently to bring thefirst two rows of moldsq' q of the succeeding. tray 0 under thedischarge-openings of the hopper, after which the aforesaid actions of the valvesand plungers and the cam mechanisms are repeated in themannerhereinbefore de-.

scribed. 'When the trays reach the front endof the machine, they are received by the supplemental conveyor-chains C" 0 and thereby carried through the cold-air box A wherebythe molded materialis cooled; When the trays have reachedthe-front end of the box AF, they are taken from-the conveyer and the .-.-molded. material removed. The traysare then placed upon a third conveyor 0 which 'carries'the trays back to-the rear end of the molding-machine, and is preferably operated by the main-driving-shaft B, which-latter conveyor is indicated by dotted lines and is unnecessary to be shown in detail,'as the same may be of any suitable and well-known conble carrier Agcomposed of sections b 12 which sections are. preferably formed at their respective meeting ends with an overlying lip c 'an'd an underlyinglip d, through which lips pass screws or bolts e a whereby said sections are detachably secured to the boards a a, thus permitting the removal of saidsections for the purpose ofi washing and cleaning the same when desired It will be seen that byreason of the chains passing over the sprocket-wheels DiD- an inflexion is naturally produced in the carrier A, which inflexall) enacts ened in the molds, wherebythc same will drop out automatically.
